A 25% discount means u paid 75%
75% of the original price is 18...
0.75x = 18.....with x being the original price
x = 18 / 0.75
x = 24 <== the original price
Answer:
<em>The probability that on a given day the supermarket will sell between 304 and 305 gallons of milk is 0.0127 or 1.27%</em>
Step-by-step explanation:
<u>Normal Distribution</u>
The graph of the Normal Distribution is also called the Bell Curve because of its particular shape. It occurs naturally in many real situations where a random variable needs to be modeled according to experimental results.
To evaluate the probability of a Normal Distribution, we need some kind of digital means because the formula cannot be computed directly in a formula. We'll use the MS Excel's specialized formula NORMDIST for the first value of x=304:
NORMDIST( 304 , 319.9 , 26.4 , true ) = 0.2735
Now for x=305:
NORMDIST( 305 , 319.9 , 26.4 , true ) = 0.2862
Both values are now subtracted to get the required probability
The probability that on a given day the supermarket will sell between 304 and 305 gallons of milk is 0.0127 or 1.27%
Answer:
Between (-0.675, 0.675)
Step-by-step explanation:
We know that a standard normal distribution curve is bell shaped unimodal , symmetrical about mean.
for thsi standard normal variate with notation z, we get mean =0 and std deviation = 1
For the middle shaded region, we find z such that the area between -z and z is 0.50 exactly half.
From standard normal distribution table, we get that z= ±0.675
Hence between z=-0.675 and z = 0.675 we get the middle region with area equal to exactly 1/2.
Between (-0.675, 0.675)
Answer:
So the dimensions are 11 1/2 yds × 15 3/4 { 11 whole number 1 by 2 yards multiplied by 15 whole number 3 by 4}
Step-by-step explanation:
Here multiplicative property will be used .
a*<u>1/a</u>= 1
1* <u>a/1</u>= a ( reciprocal)
23/147 yd × 3/14 will be multiplied with the reciprocal of the factor 2/147 to
get the original number.
23/147 yd*147/2 × 3/14*147/2
23/2 yds × 441/28
11 1/2 yds × 15 3/4
So the dimensions are 11 1/2 yds × 15 3/4 11 whole number 1 by 2 multiplied by 15 whole number 3 by 4.
